#13784: Infinite loop in compiler without undecidableXXX -------------------------------------+------------------------------------- Reporter: tysonzero | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.2.1 Component: Compiler | Version: 8.0.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by RyanGlScott): This was fixed in commit 1eec1f21268af907f59b5d5c071a9a25de7369c7 (Another major constraint-solver refactoring). In particular, this reminds me a lot of #12538, wherein overlapping multi-parameter type classes with type families also resulted in an infinite loop at compile-time. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13784#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
